How to send {{ }} from database to flask jinja2

Question

I have a case to render a template from a SQL database to jinja2.

In table shop, I have a string value like that in column shop.sms_body of table shop!

{{ location.name }} kính chào quý khách! 
Đã {{ order.days }} ngày kể từ đơn hàng {{ order.order_name }}, chúng tôi rất mong ý kiến của quý khách để ngày càng phục vụ khách hàng tốt hơn. 
Mong quý khách liên hệ chúng tôi qua số phone {{ location.phone }}, hoặc ghé thăm website {{ location.address1 }}! 
Chúng tôi chân thành cám ơn

In jinja2, my code is, i render shop, and get sms body {{ shop.sms_body|safe }}

<a class="text-left"
                       href="sms:{{ order.canonicalForm }}&body={{ shop.sms_body|safe }}"><img
                            src="/static/img/sms_icon.png" width="30px"></a>

When I click "sms message" this is what I want: {{ location.name }}.. etc have to render phone of location, but it still like image

Does anyone have a solution to this case?

Thanks in advance

Thanks! I find out solution In flask

sms_body = shop.sms_body
    print(sms_body)
    sms_body = Template(sms_body)
    list_sms_body = [sms_body.render(shop=shop, location=location, order=order) for order in orders]
    if orders == []:
        return redirect(url_for("remind.update_remind_customer", date=date))
    else:
        return render_template('/remind_customer.html', orders=orders, shop=shop, location=location, date=date,
                               next_date=next_date, pre_date=pre_date, list_sms_body=list_sms_body)

after that in html

{% if shop.use_remind_customers == True %}
            {% for index in range(orders|length) %}
                {% set order = orders[index] %}
                {% set sms_body = list_sms_body[index] %}
<a class="text-left"
                           href="sms:{{ order.canonicalForm }}&body={{ sms_body|safe }}"><img
                                src="/static/img/sms_icon.png" width="30px"></a>
{% endfor %}
{% endif %}
